<script setup lang="ts"> import { set } from "immutable"; import { ref, computed } from "vue" const count = ref(1) // const plusOne = computed(() => count.value + 1) const plusOne = computed({ get() { return count.value + 1 }, set() { count.value++ } }) /** * Make the `plusOne` writable. * So that we can get the result `plusOne` to be 3, and `count` to be 2. */ plusOne.value++ </script>

{{ plusOne }}

{{ count }}
